Description
15 20 25 30 35 -, 7710507-0 2 med endast en mätning. Avsikten med föreliggande uppfinning är därför att åstadkomma en anordning avsedd att utnyttjas exempelvis i en numerisk verktygs- maskin för kontrollmätning av den bearbetade ytan varvid man på ett enkelt sätt direkt kan erhålla mätvärden för ytans máttavvikelser i två alternativt tre koordinatriktningar. Uppfinningens kännetecken framgår därvid av de efter beskrivningen följande patentkraven. 15 20 25 30 35 -, 7710507-0 2 with only one measurement. The object of the present invention is therefore to provide a device intended to be used, for example, in a numerical machine tool for control measurement of the machined surface, whereby one can in a simple manner directly obtain measured values for the dimension deviations of the surface in two or three coordinate directions. The features of the invention appear from the claims which follow the description.
Uppfinningen kommer nu närmare att förklaras under hänvisning till bifogad ritning på vilken ' Figur l visar ett snitt genom en anordning enligt uppfinningen och Figurerna 2a - c schematiskt åskådliggör hur mätvärden erhålles med anordningen enligt uppfinningen.The invention will now be explained in more detail with reference to the accompanying drawing, in which Figure 1 shows a section through a device according to the invention and Figures 2a - c schematically illustrate how measured values are obtained with the device according to the invention.
I figur l som visar ett snitt genom en anordning enligt uppfinningen betecknas med l ett mäthus vilket är fästat vid en arm 2 som kan vara den arm som normalt uppbär verktyget i en verktygsmaskin. Vid mäthusets botten 3 är anbringad en mätsond bestående av en sfärisk avkänningskropp 9 som via en arm 8 är fästad »vid en hållare 7 som i sin tur ärförbunden med mäthusets botten 3 via ett membran 13. Membranet medger därvid att hållaren 7 dels kan förskjutas axiellt » dels kan vippas i mäthuset. Vid hållarens övre ände är anbringat en skiva 6 som av en fjäder 5 i viloläge pressas mot bottnen 3. Fjädern är därvid inspänd mellan ' 1 skivan och en med huset fastförbunden mätgivarhállare 4 som uppbär fyra givare A, B, C och D likformigt fördelade runt mäthuset, varvid för tydlighetens skull endast givarna A och B är markerade i figuren. Givarna är av konventionell typ 'exempelvis av differential transformator typ och ger utsignaler proportionella mot givarspetsarnas vertikala förskjutning. Som framgår är därvid givarspetsarna anbringade mot skivan 6. Givarnas utgângssignaler matas till en elektronikenhet ll som strömförsörjes från en strömförsörjningsenhet l0. Elektronikenheten ll e'inkopplas av en brytare l2 som påverkas då avkänningskroppen 9 rubbas ur sitt läge. Från elektronikenheten ll överföres de där behandlade signalerna från givarna A,_B, C och D lämpligen trådlöst till en prestationsenhet av konventionellt slag.In figure 1 which shows a section through a device according to the invention, 1 denotes a measuring housing which is attached to an arm 2 which may be the arm which normally supports the tool in a machine tool. Attached to the bottom 3 of the measuring housing is a measuring probe consisting of a spherical sensing body 9 which is attached via an arm 8 to a holder 7 which in turn is connected to the bottom 3 of the measuring housing via a diaphragm 13. The diaphragm allows the holder 7 to be displaced axially »Partly can be tilted in the measuring housing. Attached to the upper end of the holder is a disc 6 which is pressed against the bottom 3 by a spring 5 in the rest position, the spring is then clamped between the disc and a measuring sensor holder 4 connected to the housing which carries four sensors A, B, C and D uniformly distributed around the measuring housing, whereby for the sake of clarity only the sensors A and B are marked in the figure. The sensors are of the conventional type, for example of the differential transformer type, and provide output signals proportional to the vertical displacement of the sensor tips. As can be seen, the sensor tips are attached to the disc 6. The output signals of the sensors are fed to an electronics unit 11 which is supplied with power from a power supply unit 10. The electronic unit 11 is switched on by a switch 12 which is actuated when the sensing body 9 is disturbed from its position. From the electronics unit 11, the signals processed therein are transmitted from the sensors A, _B, C and D suitably wirelessly to a performance unit of a conventional type.
Hur den ovan beskrivna anordningen i princip fungerar skall nu beskrivas med hjälp av figur 2 a - c som schematiskt visar sambandet mellan givarnas A, B, C och D utgångssignaler och rörelserna hos avkänningskroppen 9. Vid kontrollmät- ning av en yta inställes mäthuset så att avkänningskroppen 9 koumer i kontakt med ytan, varefter mäthuset föres längs koordinatlinjer.parallella med den form den bearbetade ytan skall ha antagit. Om ytans faktiska utseende därvid avviker från den önskade kommer avkänningskroppen 9 att röra sig relativt mäthuset l. ß 7710507-0 I figur 2 visas hur dessa relativa rörelser påverkar givarna. Som framgår av figurerna 2a och 2b kommer därvid avkänningskroppens horisontella rörelse längs X- respektive Y-koordinataxlarna att bli proportionell mot skillnaden hos givarutslaget hos givarna A, B respektive D, C, medan en vertikal rörelse ger ett givarutslag proportionellt mot sumnan av de fyra givarnas utgångs- signaler. Den signalbehandling som erfordras för att direkt erhålla mätvärden svarande mot mätspetsens rörelse i de tre koordinatriktningarna blir således mycket enkelt. Det inses vidare att för fastläggande av skivans 6 exakta läge endast tre lägesgivare erfordras ehuru signalbehandlingen då blir något mer komplicerad. önskas en bestänning av endast två koordinater krävs givetvis endast två givare.How the device described above works in principle will now be described with the aid of Figures 2 a - c which schematically show the connection between the output signals of the sensors A, B, C and D and the movements of the sensing body 9. When controlling a surface, the measuring housing is set so that the sensing body 9 comes into contact with the surface, after which the measuring housing is passed along coordinate lines. parallel to the shape the machined surface must have assumed. If the actual appearance of the surface then deviates from the desired one, the sensing body 9 will move relative to the measuring housing 1. ß 7710507-0 Figure 2 shows how these relative movements affect the sensors. As can be seen from Figures 2a and 2b, the horizontal movement of the sensing body along the X and Y coordinate axes will then be proportional to the difference in the sensor range of the sensors A, B and D, C, respectively, while a vertical movement gives a sensor range proportional to the sum of the four sensors. output signals. The signal processing required to directly obtain measured values corresponding to the movement of the measuring tip in the three coordinate directions thus becomes very simple. It is further understood that for determining the exact position of the disc 6 only three position sensors are required, although the signal processing then becomes somewhat more complicated. If a population of only two coordinates is desired, of course only two sensors are required.
